I agree with mouse that having one or more children helps them cope with things easier than just one. I have only one 10 year old son and he through the years has been lonely, and depends on us to play with him that is until he met friends his age and got older where they could come over and play. My son is also trying to fix things between me and my husband even though we've told him it is not his job or responsibility. He hates to see us argue and not get along , which occurs quite frequently. So I say if your marriage is secure and you both want more children to go ahead. As long as it is for the right reason. I wish I could have had at least one more child but it didn't happen. Now I'm just about too old and forget about this our marriage is almost over the rocks. I don't know which one of us is going to give up first. I guess the person who has had enough and can't take it anymore. Best wishes to you though.
